Earlier this month Microsoft released the KB5026361 update to fix some security vulnerabilities in the Windows 10 system. However, it seems that this update also brings some problems. According to Reddit and Microsoft feedback center users, after installing the latest update, Windows 10 system has various problems.
One of the most common problems is the Blue Screen of Death (BSoD) with the error code “PROCESS1 INITIALIZATION FAILED”. According to a previous Microsoft article, this error code is related to the Bootcat file. According to the article, the problem is caused by a corrupted or changed size of the Bootcat.cache file. Microsoft recommends booting with the Windows installation disk and deleting the Bootcat.cache file to solve the problem. However, this article was originally written for Windows 7, so it is not clear if it applies to Windows 10. However, some users in the Microsoft Feedback Center reported that they successfully resolved the issue by booting from a USB drive using the Windows 10 installation image and manually starting the AMD RAID driver through a command prompt, then performing a boot repair.
In addition, users have reported other issues such as error code 0x800f0922 when installing updates, random system reboots, a series of error messages popping up, update failures and crashes. Microsoft has not yet responded to these reports, so the exact cause of the problem or the scope of its impact is not known.
Recommends enabling System Restore on the Windows installation disk (usually the C drive) and creating a System Restore point before installing the Patch Tuesday update, as well as doing so before installing third-party software on your system.
